I may attempt a shuttlebay interior, maybe have one door open with a few shuttles. If I do then I'll probably slip in a ship from another universe, Galactica or Star Wars.
I've actually done some work, I disassembled the kit I did in 95 and lets say it's not a great kit. I marked off the spots to remove/fill on the saucer, removed the impulse to mover forward about 3/4" and made a template for covering up the greebled recesses.
All the little bumps on the saucer sucked so they are going, all the current windows will be filled and redrilled.
